(From company literature) Tamrac 5744 Velocity 4 Micro Sling Pack. The Velocity 4 - Micro Sling Pack, Tamrac's smallest sling pack, holds a digital camera or compact camcorder and accessories (like an AC adapter). The sling pack design is versatile to carry like a backpack, but can be easily accessed by sliding the pack around to the front. The front pocket features Tamrac's U.S. patented Memory & Battery Management System™ that uses red flags to identify available memory cards from ones that are used up. Other features include: Speed Flap™ Top, an adjustable, foam-padded divider, and an accessory pocket in the top for lens cleaning paper. Add Tamrac accessories using the attachment slots for our Strap Accessory System™ (S.A.S™) products to customize this small sling pack.
